Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contain a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
What are the uses of square tubes?
Rectangular pipe is a kind of steel pipe for construction. It has various uses. It can be divided into square pipe for decoration, square pipe for machine tool equipment, square pipe for mechanical industry, square pipe for chemical industry, square pipe for steel structure, Square tubes for shipbuilding, square tubes for automobiles, square tubes for steel beams and columns, square tubes for special purposes, etc.
The specific uses are:
1. Used as a pipeline for transporting fluids: it can transport oil, natural gas, water, gas, steam and other fluids.
2. Manufacture of mechanical parts and engineering structures: The square tube is light in weight and does not affect the bending and torsional strength, so it is also widely used in the manufacture of mechanical parts and engineering structures.
3. Production of weapons: It can be used to produce various conventional weapons, barrels, shells, etc.
4. Building structure: used as building steel for beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.
Note:
1. Free sampling, 100% after-sales quality assurance, and support for any payment method;
2. All other specifications of carbon steel pipes can be provided according to your requirements (OEM and ODM)! You will get the ex factory price from Royal Group.

Precautions for packaging and transportation of carbon steel pipes
1. Carbon Steel Pipe must be protected from damage caused by collision, extrusion and cuts during transportation, storage and use.
2. When using carbon steel pipes, you should follow the corresponding safety operating procedures and pay attention to prevent explosions, fires, poisoning and other accidents.
3. During use, A36 Steel Pipe should avoid contact with high temperatures, corrosive media, etc. If used in these environments, carbon steel pipes made of special materials such as high temperature resistance and corrosion resistance should be selected.
4. When selecting carbon steel pipes, Carbon Steel Pipe of suitable materials and specifications should be selected based on comprehensive considerations such as the use environment, medium properties, pressure, temperature and other factors.
5. Before carbon steel pipes are used, necessary inspections and tests should be carried out to ensure that their quality meets the requirements.
Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)
